German submarine U-154 was a Type IXC U-boat of Nazi Germany's Kriegsmarine built for service during World War II. The keel for this boat was laid down on 21 September 1940 at the DeSchiMAG AG Weser yard in Bremen, Germany as yard number 996. She was launched on 21 April 1941 and commissioned on 2 August under the command of Korvettenkapitän Walther Kölle.

The submarine began her service life with training as part of the 4th U-boat Flotilla; moving on to the 2nd flotilla for operations. She conducted eight patrols, sinking ten ships.

She was sunk by American destroyers in July 1944.

German Type IXC submarines were slightly larger than the original Type IXBs. U-154 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged. The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 metric horsepower (740 kW; 990 shp) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
